UNESCO says the designation is meant to safeguard and raise awareness about forms of cultural heritage — often passed down from generation to generation — before they die out. Around three dozen other cultural practices were also added to this year's intangible list, including Kumbh Mela— an event in India when pilgrims bathe in a sacred river and Uilleann piping— a type of Irish music played by a particular bagpipe.

As for pizzaiuolo, it is more than a slice of sustenance, itis a form of artistry with a deep history baked right in. Pizzaiulo "fosters social gatherings and intergenerational exchange" and the "Pizzaiuoli (pizza-makers) are a living link for the communities concerned," says UNESCO (the United Nations Educational, Scientific and Cultural Organization).

The practice of pizzaiuolo consists of a few stages: first the dough (water, flour, salt and yeast) must be kneaded by fist for at least 15 minutes, then allowed to rest and rise for 12 hours. Next balls or panetti are formed and left to rest some more. Then the dough is stretched and beaten into a circle. Finally the toppings are added, and the pizza is placed in the oven and rotated with a pizza shovel to ensure uniform baking. Two minutes is all it takes.

The Naples-based Associazione Verace Pizza Napoletana (True Neapolitan Pizza) will only issue its trademark to restaurants that follow even more stringent guidelines. But the result should be a pizza for the senses with "the flavor of well-baked bread. The slightly acidic flavor of the densely enriched tomatoes, mixed with the characteristic aroma of the oregano, garlic or basil ensures that the pizza, as it comes out from the oven, delivers its characteristic aroma."

Pepperoni and pineapple lovers are out of luck. The association says only two kinds of pie are authentic: marinara pizza with tomato, oil, oregano and garlic and margarita pizza with the addition of cheese and basil.

Pizzaiuoli can take it to the next level by stretching and tossing the pie in a doughy display of acrobatics at international competitions.

When news of the UNESCO recognition broke in Naples, pizza-makers handed out free slices on the street to celebrate, according to the BBC. Two million people had reportedly signed a petition supporting the piazzaiulo application.
